The black grilles are available from BMW, I think they were about £75 for the two; black (dark chrome) exhaust tips are from the 'Sport' line, and are around £60 for the two; the roundels are genuine carbon fiber (black, not grey, it's just the photo) which I have for the bonnet/boot/wheels and steering wheel, they were around £50 from a chap on eBay; the black/grey little M Sport badges (x5) were also from eBay, about £8 for all 5; anyone is welcome to PM me and I will give you some links
